Where is the best manufacturer of solar lawn lights?

In most cases, solar lawn lights receive ultra-bright white LEDs. The time (lifespan) when the luminous flux retention rate of ultra-bright white LEDs reaches 50% of the initial intensity at 20ma is less than 10,000 hours. In the environment, led is not the best solar lawn light source, unless it is a low-level solar lawn light with a service life of only 1 to 2 years, which is about a solar lawn light below 1w. To withstand the solar lawn lights above 1w, it is best to use three-color primary color high-efficiency energy-saving lamps. At that time, some solar lawn lights used 30~40 ultra-bright white LEDs with an input power of 2W or more. In this environment, if you use three-color primary color high-efficiency energy-saving lamps, the value is only 1/10 of the LEDs, and the luminous flux is the original Now it has developed a 2~10w low-voltage DC three-color primary color high-efficiency energy-saving lamp with a lifespan of 6,000 hours. According to the above analysis, we believe that the low-power solar lawn lights below 1w that have the effect of adjusting light and shade and frequent switching, usually use LEDs as the light source. However, when using ultra-bright white LEDs, pay attention to the question of the luminous flux retention rate, otherwise it will easily lead to confusion. It is more reasonable to use three-color primary color high-efficiency energy-saving lamps to withstand solar lawn lights with high power. What is important here is that the above conclusion is only an analysis at the time. When the level of LED technology improves and the value declines, the above conclusion needs to be reformed. To resist solar lawn lights, from the aspects of reliability, performance-value ratio, color temperature, and luminous power, we thought that the ideal light source was probably three-color primary color high-efficiency energy-saving lamps.
